. The atoll of Funafuti, Ellice group: its zoology, botany, ethnology, and general structure based on collections made by Mrs. Charles Hedley, of the Australian museum, Sydney, N. S. W. THE MOLLUSCA—HEDLEY. 441. Fig. 28. their own diameter from their neighbours in a row, and linked to them by an inconspicuous raised coloured ridge. Between the gemmules the surface is microscopically shagreened and finely spirally grooved. The aperture is perpendicular, and nearly square; outer lip thickened and reflected, the right margin crossing the canal in a spur; anal notch deep; semicircular canal short, blunt, oblique. Length 5, breadth 2 mm. Several specimens alive in the Funafuti lagoon. The peculiar colouration of this species facilitates recognition. Even the unaided eye can detect the two chocolate lines on the base and spire, and the white spiral band ascending the inter- mediate whorls. This colour scheme I have endeavoured to convey in Fig. 28. In colour T. cinguliferus, Pease, appears to resemble torquatus, but the figure given by Langkavel, copied and coloured by Tryon, represents a stouter shell with a different aperture. The group (Mastonia, according to Tryon) to which this belongs, might be conveniently divided into two sections, having a one- keeled and a two-keeled protoconch, respectively. The present species with T. dolicha and T. eagle would belong to the former. I have collected T. torquatus also at Port Moresby, British New Guinea. Triforis ruber, Hinds. (Fig. 29). Hinds, Ann. Mag.
